This is a fun and sturdy floor puzzle that my two boys absolutely love! Each night, my two boys (aged 4 and 2) and i, pick one puzzle to build before bed time, it settles them down, and they see it through, from start to finish. The pieces are a great size and quite strong and durable. We already own 3 crocodile Creek puzzles and hope to continue to expand our collection as they're fantastic! My 4yo can build them on his own with a little help here and there. We guide our 2yo with 2 pieces that'll go together so he still feels a part of it. Oh, and we usually end up building all three, instead of just the one. Hahaha!
